Head-mounted display

Abstract

A head-mounted display (HMD) 1 , which is operated by a gesture operation performed by a user 3 , is provided with a distance image acquisition unit 106 that detects a gesture operation, a position information acquisition unit 103 that acquires position information of the HMD 1 , and a communication unit 2 that performs communication with another HMD 1 ′. A control unit 205 sets and displays an operating space 600 where a gesture operation performed by the user 3 is valid, exchanges position information and operating space information of the host HMD 1 and the other HMD 1 therebetween by the communication unit 2 , and adjusts the operating space of the host HMD so that the operating space 600 and an operating space 600 ′ of the other HMD 1 do not overlap each other.

The invention claimed is: 
     
       1. A head-mounted display comprising:
 a projector configured to project an image; 
 a see-through lens configured to superimpose the image projected by the projector on a nearby space and display the image as a mixed reality object; 
 a receiver configured to receive position information of the head-mounted display; 
 a communication interface; and 
 a controller, 
 wherein the controller is configured to: 
 set a first operating space in which a gesture operation of a user of the head-mounted display may be performed, 
 control the projector to display an image of the first operating space and an image of an operation object as the mixed reality object via the see-through lens, the operation object is an object operated by the gesture operation of the user of the head-mounted display and is displayed in the first operating space, 
 acquire information of a position and a second operating space of another apparatus by the communication interface, the second operating space is a space in which a gesture operation of a user of the another apparatus may be performed, 
 determine whether the first operating space overlaps with the second operating space based on the position information of the head-mounted display received by the receiver and the information of the position and the second operating space of the another apparatus acquired by the communication interface, 
 reduce a size of the first operating space so as not to overlap the second operating space if the first operating space overlaps with the second operating space, and 
 control the projector so that a part of the operating object is set to non-display if an image of the reduced size first operating space is displayed as the mixed reality object via the see-through lens, and 
 control the communication interface so as to communicate with a smartphone and switch an operation corresponding to the non-displayed object from the gesture operation to an operation by the smartphone if the part of the operating object is set to non-display. 
 
     
     
       2. The head-mounted display according to  claim 1 , wherein the controller is configured to notify the user of the head-mounted display that a part of the gesture operation is limited if the part of the operating object is set to non-display. 
     
     
       3. The head-mounted display according to  claim 1 , wherein the operation object is for performing an operation of selection, viewing initiation, or viewing termination of a content. 
     
     
       4. The head-mounted display according to  claim 1 , further comprising a camera configured to detect the gesture operation of the user of the head-mounted display. 
     
     
       5. A display apparatus comprising:
 a projector configured to project an image; 
 a display configured to superimpose the image projected by the projector on a nearby space and display the image as a mixed reality object; 
 a receiver configured to receive position information of the display apparatus; 
 a communication interface; and 
 a controller, 
 wherein the controller is configured to: 
 set a first operating space in which a gesture operation of a user of the display apparatus may be performed, 
 control the projector to display an image of the first operating space and an image of an operation object as the mixed reality object via the display, the operation object is an object operated by the gesture operation of the user of the display apparatus and is displayed in the first operating space, 
 acquire information of a position and a second operating space of another apparatus by the communication interface, the second operating space is a space in which a gesture operation of a user of the another apparatus may be performed, 
 determine whether the first operating space overlaps with the second operating space based on the position information of the display apparatus received by the receiver and the information of the position and the second operating space of the another apparatus acquired by the communication interface, 
 reduce a size of the first operating space so as not to overlap the second operating space if the first operating space overlaps with the second operating space, 
 control the projector so that a part of the operating object is set to non-display if an image of the reduced size first operating space is displayed as the mixed reality object via the display, and 
 control the communication interface so as to communicate with a smartphone and switch an operation corresponding to the non-displayed object from the gesture operation to an operation by the smartphone if the part of the operating object is set to non-display. 
 
     
     
       6. The display apparatus according to  claim 5 , wherein the controller is configured to notify the user of the display apparatus that a part of the gesture operation is limited if the part of the operating object is set to non-display. 
     
     
       7. The display apparatus according to  claim 5 , wherein the operation object is for performing an operation of selection, viewing initiation, or viewing termination of a content. 
     
     
       8. The display apparatus according to  claim 5 , further comprising a camera configured to detect the gesture operation of the user of the display apparatus.
